Datamined Game Win/Loss Statistics - Page 4

Ties. Sometimes, in games where my opponent quits early, like 2 minutes in, before any action happened, I check my match history and it doesn't update as a win or lose until a day later.

But that number seems a bit too high. There are several possibilities.

1. Wins update faster than losses.
2. Data is missing from servers
3. Disconnects count as win and tie, but appears as a -0 loss
4. Placement matches do not count towards ladder ranking, so if you are in placement and you've played against someone in ladder, your loss is not recorded, but his win is. Or something of the sort. Seems the most plausible.

A tie wouldn't result in a win for one player though. Your other 4 points seem reasonable, I think that it has to do with people still being in placement, because I didn't see anything in the OP about that.

I do not think these numbers are useful.

The matchmaking system tries to push everyone to a 50% win rate. If there is an imbalance in the game, the player with the stronger race will start playing harder opponents of weaker races until his win rate is 50%. This negative feedback ensures that the races will always appear balanced. The win rates need to be weighted by the underlying matchmaking parameters, and we don't have access to that information.

Props nonetheless for putting this together. It's pretty cool to see .

That doesn't make any sense whatsoever. Players are matched against other players, regardless of what race they play.

Right, but if a person gives themselves a handicap, the system will generally find an equilibrium where they are at 50%. It doesn't matter what you do as long as you are consistent. You could decide to only ever build one extractor, and you will keep losing until it finds truly terrible players where you are at 50%. You would never conclude that building only one extractor is just as good as building two, but you would still have a 50% win rate with it.

Another possibility is that the bottom bronze players who have only played a few games haven't gone on the forums ( and may not at all)

You don't really understand how this data is compiled, do you? It's done by looking up the win-loss ratio of every player, assuming that they play exclusively their "most played" race, then totaling them up. Not individual matchups.
